There are only 4 radii in a circle.
Which diagram shows a circle with a point marked in the circle and not on the circle?
Is it possible that the circumference of a circle is 8 meters and its diameter is 4 meters?
Is there sufficient data to determine that
\( GH=AB \)
M is the center of the circle.
Perhaps \( AB=CD \)
There are only 4 radii in a circle.
A radius is a straight line that connects the center of the circle with a point on the circle itself.
Therefore, the answer is incorrect, as there are infinite radii.
False
Which diagram shows a circle with a point marked in the circle and not on the circle?
The interpretation of "in a circle" is inside the circle.
In diagrams a'-d' the point is on the circle, and in diagram c' the point is outside the circle.
Is it possible that the circumference of a circle is 8 meters and its diameter is 4 meters?
To calculate, we will use the formula:
Pi is the ratio between the circumference of the circle and the diameter of the circle.
The diameter is equal to 2 radii.
Let's substitute the given data into the formula:
Therefore, this situation is not possible.
Impossible
